Specification of Letters Patent.

Application led November 14, 1914, Serial No. 872,085. Renewed April 27, 1916. Seral'No. 94,050.

To all whom t may concern Be it known that I, EvnRETT L. THOMP- SON, a citizen of the United States, and resident of Dover, county of Morris, and State of New Jersey, have made a certain new and useful Invention Relating to Telephonie Fire-Alarm Apparatus, of which the following is a specification, taken in connection with the accompanying drawing, which forms part of the same.

This invention relates especially to apparatus for automatically transmitting fire alarm signals over 'regular telephone circuits of any suitable character. A separate telephone connection may be provided, if desired, or if preferred a standard desk or other telephone set may be so arranged in connection with the alarm transmitting mechanism as to automatically call the central station operator in the event of fire or similar emergency and transmit thereto an articulate or other suitable danger signal.

In the accompanying drawings which show in a somewhat diagrammatic way illustrative embodiments of this invention Figure 1 is a perspective diagrammatic view showing one form of apparatus. Fig. 2 shows a modified arrangement for use in connection therewith; and Fig. 3 is another diagram showing a different form of alarm transmitting mechanism.

This invention com rises the use of any suitable alarm operatlng mechanism which is actuated in the event of fire or on the operation of suitable fire extinguishing apparatus which comes into action when fire occurs so that an articulate or any other suitable audible or other alarm signal may be transmitted over a telephone circuit after the central station operator has been called by this automatic alarm apparatus. The signal lights, annunciator drops or other i11- dicating devices of the central station equipment enable the telephone operator to cletermine the subscribers number and the location of tluJ calling station. so that when a lire alarm signal of any suitable character is automatically transmitted in this way the location of the fire is definitely known as being on the subscribers premises and the central station operator can thus communicate this information to the fire headquarters or other suitable fire control station. If desired, the alarm signal may be of an articulate character as by sending over the telephone b means of a suitable phonograph the wor s Fire here. Send in alarm, or some equivalent expression which can be automatically repeated in connection, if desired, with a periodic flashing of the signal light so as to continually call the attention of the central station operator to this alarm for any desired number of minutes while the alarm apparatus is in operation. It is not, however, necessary to use a phonographic or other articulate alarm si nal since under fire emergency conditions t e apparatus may, for instance, cause a bell to be rung in such way as to transmit this sound to the central station operator either in conv nection with a periodically repeated call signal or otherwise so as to make a distinctive and definite alarm signal to the operator which Will show that a ire has occurred on the premises of that particular telephone subscriber. In this way` the telephone circuits and central station equipment which are so Widely installed can be efficiently utilized for the transmission of ydistinctive ire alarms and a corresponding advance made in the effectiveness of fire protection throughout many districts ofthe country.

In the form of apparatus shown diagram-` matically in Fig. 1 a standard desk telephone set is shown as coperating with the alarm transmitting mechanism and if de- ,sired this telephone set can be normally used throughout the day in the ordinary way for telephoning messages so long as the instruments are replaced in the alarm transmitting positionindicated in connection with the other apparatus. proper position of the telephone instruments in this connection the casing is preferably provided with an ,upper portion or partition 62 which fits quite closely above the top of the transmitter 51, the mouthpiece of which is adapted to enter the flaring and alining end 19 of the alarm transmitting funnel which may be connected with the phonograph or other alarm'mcchanism. The regular support and base 1, i2 of the instrument may also coperate with additional aliningt devices, such, for instance, as the alining socket 63 in the base portion 3 of the casing into which the base of the instrument may be first placed andpthen the transmitter swung forward beneath the partition or casing` 62 until the mouth-piece enters the flaring funnel end 19. In this Way In order to insure the telephone hook up and down periodically so .lever o a definite positioning of the telephone instrument is secured and the hook or receiver support 4 is brought beneath the lifting call 7 and into proper coperation therewith to be lifted by any suitable mechanism under emergency conditions. This calls the attention of the Icentral station operator to this line and on plugging into the circuit in the usual way the operator at once hears the articulate or other alarm signal 'which is au tomatically transmitted over this line so that the definite fire alarm is automatically given to the operator in the telephone central station. As indicated the lifting call lever 5 which may be provided with a suitable frictional or irregular upper surface 74 to engage the telephone hook without undesirable slipping may rbe ipivoted about the pin 73, for instance, and swung upward under emergency conditions by any suitable mechanism such as the pin 72 in the upper end 74 of this lever with which cooperates the slotted end 71 of the connector 6 which may be given a single or periodic oscillation by any suitable mechanism. As indicated the end of this connector may be operated by the crank pin or pivot 69 in the disk 8 which is automatically rotated by a suitable spring '9 on its shaft or stem 68 or by any other mo- ;tor when the firev or other emergency condi- 'or receiver support of the telephone and give the usual call signal over the connected telephone circuit to the central station. If

desired a suitable spring detent such as 7 may be used in connection with the call lever so that when it is raised the upper ond of the lever is engaged and held by this detent in raised calling position so that the usual signal light is kept lighted on the central station switchboard. If, hpwever, this detent is not used the call lever moves the as to give a periodic visual signal at the central station, the phonograph record being, of

course, arranged so as-to give the desired articulate signal when the hook is raised suficiently to close the calling and transmitting circuit. l

An articulate ala-rm signal may be transmitted over the telephone circuit by the use of any suitable phonograph mechanism which may, for instance, comprise a metallic or other disk record 16 preferably having la continuous or repeating sound groove 65 formed therein, so that the needle 64 of the phonograph travels around this record groove in the usual way until the inner groove is reached- When a deeper or transfer groove such as .66, leads the lneedle out to the outer groove again so as to continuouslyv repeat the articulate or verbal alarm signal which may be in any desired words. As indicated in connection with this record the alarm signal may, for example, be or comprise the words Eire here. Send alarm, which would bc continuously repeated so long as the phonograph disk was rotated. The other parts of the phonograph mechanism may be of any desired character and may comprise the usual sound box having a diaphragm 17 actuated j by the needle 64 which is arranged in any desired way so as to follow the record groove, the sound being transmitted through the tone arm and into the flaring horn or passage 18 communicating with the telephone transmtter. It is also important that an alarm shall be given by the transmitting apparatus throughout the adjacent room or premises so as to notify the occupants of the danger of fire and in many cases such locally given articulate fire alarm signals are of considerable value without any telephone transmission thereof. 'if desired such local audible alarms may be readily given by providing another horn or passage 48 communicating with the tone arm and connected if desired with the upper portion of the transmitter casing as by having the end of this passage 49 secured thereto so that a large Sound opening or horn 50 is provided and the articulate or other alarm signal made distinctly audible throughout the adjacent rooms of the building so that emergency measures may be taken by the occupants. It is of course desirable tol have the size and character of these passages 18 and 48 so proportioned as to give throughout the adjacent portion of the building aV loud alarm signal of suiiicient intensity to wake such occupants as may be asleep, while at the same time the intensity of the sound in the` telephone transmitter is not undesirably loud. It is of course in all cases unnecessary to have such closed sound passages between the phonograph and the telephone transmitter since the phonography may be formed with a, large horn or delivery opening through which the alarm signal is transmitted under emergency conditions and the telephone instrument may be located anywhere within reasonable distance where it can receive andv transmit this articulate or other audible alarm sig- A nal to the central station. For this reason 1t is not in all cases necessary to have for this purpose any very definite positioning of the telephone instrument 'with respect to the transmitting devices, although it is desirable in most cases to insure proper cooperation between the calling devices and the hook or other coperating portion of the telephone instrument. This phonograph may be operated by any suitable gearing or mechanism such as the drive gear 12 on the shaft 68 operated by the spring 9 and this gear may be in mesh With the pinion 13 driving` the intermediate gear 14 meshing with the pinion 15 on the shaft or stud 67 carrying the phonograph record 16. By such a spring motor the record may be continuously rotated for any desired number of minutes so as to keep repeating the alarm signal and insure its receipt by the operator of the central telephone exchange or other supervising station.

The automatic fire detecting or other alarm operating devices which effect the operation of this alarm transmitting mechanism may be of any desired or suitable character and maybe arranged for actuation in case of an unusually high or rapid rise of temperature in any part of the protected premises, or in case of the operation of any automatic or other fire extinguishing apparatus locatedl therein. As an example of these actuating devices an air alarm tube, such as 21, is shown diagrammatically as arranged tov extend around various parts of the house and this tube is connected with an alarm casing 20 having therein the flexible actuating diaphragm 80 provided with the alarm contact 81. In the event of an unusually rapid rise of temperature'the air in this small tube is expanded so rapidly as to :torce outward the diaphragm and connected contact so as to bring the latter into electrical contact With the coperating contact member 82, thus completing the elect-ric circuit through batltery 83 and Wires 84, 85 so as to actuate the alarm operating magnet 11 and swing over the armature 7 7 on the trigger arm 10 so as to release the connected transmitting mechanism. As usual in these air alarm devices a suitable leak or regulating connection 180 may be made between the tube and the outer air at any suitable point so as to take care of the normalgradualftemperature changes and prevent their giving any alarm signals. Another form of actuating device is shown in connection with an automatic pressure tank such as the chemical mixing tank V22 which may be of the construction shown and described in the patents to Cooney` such as 1,075,017 of October 7 1913. etc. This tank maycoinmunicate ivith a suitable distribut-v ing system comprising the riser or supply pipe 25 and the automatic sprinkler heads 28 arranged at suitable intervals about the building; and hose connections, such as 27, may also be provided at suitable points so as to come into operation When the con# nected valve 26 is opened. In the event of fire these devices operate automatically and the mixture of chemicals creates a high pressure Within the mixing tank 22 so that this fluid pressure may be readily transmltted to any part of the building through the connecf' tion or pipe 23. As indicated this pipe may communicate With the alarm actuating casing 24 having a resilient diaphragm 78 connected .therewith so that under fire emergency conditions the fluid pressure will move this diaphragm to the left, thus forcing the connected stud or projection 79 against the end of the trigger arm and mechanically oscillating this arm so as to release the transmitting mechanism as previously described. The alarm transmitting device may also be operated on the emergency operation of any form of automatic sprinkler system by including in the actuating devices the alarm valves or other movable parts of any of the ordinary Wet pipe or dry pipesprinkler systems. For example, such a system as is shown and described in the Thompson Patent -734,049 of November 8, 1903,A may be used for this purpose, the diaphragm circuit closer being available to give an electric alarm, and the Water pipe connection used to operate the mechanicalv alarm is 01:' course available to mechanically operate any portion of the transmitting devices or even to directly give the call signal over the telephone as by mechanically raising the telephone receiver as it rests on the hook of the instrument or morel directly by raising the hook itself.

In case it is not desired to have an articulate alarm signal transmitted over the telephone circuit to the central station any other desired audible signal maybe substituted and a corresponding change made in the alarm transmitting mechanism. Fig. shows an arrangement in which a bell is used to give an alarm signal and this bell may be included in series in the alarm operating circuit 84, 85 shown in connection with Fig. l, and thus give under ire or emergency conditions a loud alarm signal which is not only distinctly audible to the occupants of the adjacent premises, but also readily transmitted through a telephone instrument anywhere in theneighborhood so as to give an alarm to the central station operator. The bell magnet 111 is so connected as to bel intermittently energized because of the usual interrupter included in this circuit so as to intermittently attract its ai'inature 112 and continuously ring the cooperating bell in the usual 'Way as long as the battery or other source ofelecti'icity remains effective. As indicated this bell may be mounted in any desired way in the vicinity of the mouth-piece 61 of the telephone transmitter 51 so as to transmit this loud distinctive audible ala-rm signal over the telephone circuit under such emergency conditions after the calling devices operate.

lf desired the ala-rm signals may be transmitted over the regular telephone circuits by the use of a special telephone transmitting device which may be connected to the telephone circuits in the subscribershouse. Fig. 3 shows diagrammatically such an arrangement which may comprise a phonograph where articulate signals are desired.

As indicated the phonograph cylinder may Aver 39 thus alter the electrical resistance between these two contacts and allow an oscillatory current to pass between the connected wires 120, 121 when this circuit is closed.

Normally, however, this circuit is open and the shunt high resistance circuit across the outside telephone line 123, 124 is normally maintained through a highresistance of any character, such for instance, as the signal bell 40, this shunt circuit being shown as comprising the wires 125 and 126 on either side of this bell.

Under fire emergency conditions the telephone call and transmitting circuit through the microphone is automatically closed so as togive at the central station any desired visual or other call signal which may be made distinctive by giving it a periodic or repeating character, and Vat the same time the phonograph is set in operation to give any desired articulate or" other alarm signal over the telephone circuit so as to be received by the central station operator. This may be effected by the mechanism diagrammatically illustrated as comprising the Spiral spring or other motor device 94 arranged on the shaft 134 carrying the gear 34 so that the spring tends to rotate this shaft and gear. Their rotation is, however, normally prevented by a suitable device which may comprise the notch 96 in the connected disk 29 with which the trigger arm or lever 30 normally coperates as indicated. When, however, this trigger is electrically or mechanically withdrawn from the notch the disk and connected parts are set in rotation by the spring and through any suit` able gearing the phonograph may be con- ,tinuously operated for the desired time.

The gear 34, for instance, may be in mesh with the pinion 35 carrying on the same shaft the intermediate gear 36 which may mesh with the pinion l37 secured to the phonograph record cylinder 38. The tlephone call circuit may be simultaneously operated by any connected mechanism and it desired this may be effected by suitable contacts coperating with the disk 29 which for this purpose may be formed with a suit- 1 able recess 95. The spring contact 32 normally lies within this recess so as to be out of contact with the coperating spring member 33 and break the circuit between the wires 121, 122. Vhen, however, the disk rotates under emergency, conditions the contacts are brought together and held in electrical contact whenever the normal circumference of this disk y29 engages the end of the spring contact 32. In this way lthe cenr tral station signal light, such as 42, may be periodically illuminated and extinguished for short periods once or twice for every revolution of the disk 29, the retainer notch 9G being if desired made of suflicient size to allow the momentary extinguishing of this light as it passes slowly under the contact 32. In this way a periodic distinctive flashing of the signal light is caused and simultaneously an articulate or verbal signal f is transmitted to the central station by the phonograph which may be so timed as to repeat the desired words `during the period when the telephone call and transmitting circuit is automatically closed by this mechanism. Thus the operators attention having been called to this line and the operators circuit plugged in by the usual plug.

character whatever and may for example.

comprise electrical or other connections with a pressure tank, such as 47, which may be of the chemical mixing type referred to in the Cooney patents. This tank may, for example, be provided with a flexible diaphragm 46 so that under emergency conditions the increased pressure forces upward this diaphragm and the connected stud 102 which thus makes contact with the coperating springv contact 103 and closes the circuit 99, through the battery-101 so as to energize the operating magnet 31 and attract the armature 98 which as indicated may be directly connected to the trigger arm 30. Other thermal or emergency detector devices may also be used, such for instance, as the fusible link device indicated as comprising the spring arms 107, 108 secured to the insulating block 106 and provided at their outer ends with suitable electrical contacts 109, 110; f These contacts are normally kept apart by a fusible link 45 comprising suitable solder or the like, which is adapted on a dangerous rise of temperature, to soften or melt so as to release this link and allow the contacts to be brought together. This closes the alarm actuating circuit between the wires 104, 105 which are in shunt around the other alarm circuit and serve to actuate in the same way the'alarm operating magnet 3l and withdraw the trigger arm so as to allow the alarm transmitting mechanism to operate as previously described.
